Sulphur dioxide (SO2) is usually used in winemaking due to its effectiveness as an antimicrobial and antioxidant agent. However, there growing interest finding alternatives SO2 because of adverse effects on human health. Therefore, this work, a low-SO2-producing Saccharomyces cerevisiae strain was selected the AIR-MIXINGTM M.ITM (A.M.) system, capable determining high extraction polyphenols, pr...

Background: Pollutant gases such as Carbon Monoxide (CO), Nitrogen Dioxide (NO2) and Sulphur (SO2) are released during certain anthropogenic activities including cooking with biomass. This study evaluated the air quality index of CO, NO2 SO2 emissions outdoor biomass combustion in Niger Delta region Nigeria. Materials Methods: Triplicate sampling was carried out at 3 distances 4 different state...

Despite the success of the US Environmental Protection Agency’s Acid Rain Program in reducing national sulfur dioxide emissions from electricity generation in a timely and costsaving manner, expected improvements in the environment have not followed in a linear fashion. While ambient sulfur dioxide (SO2) concentrations and acid deposition have decreased across the US, the health and ecological ...

This study investigates the requirements for modeling of acid sulfite pulping with regard to the recovery of cooking chemicals, especially SO2. Such a model has to predict the temporal change of SO2 distribution on solid, liquid and gaseous phase in the digester throughout the whole pulping process, dependent on the pulping parameters: total SO2, free SO2, liquor-towood ratio, temporal temperat...

OBJECTIVES Outdoor air pollution has consistently been shown to predict mortality. The finding that this association is stronger in infants than in children or adults raises the question whether air pollution could also be related to pregnancy outcomes--such as birthweight and stillbirth. The association between outdoor air pollution and stillbirths and low birthweight in the Czech Republic, wh...

To assess effects of sodium fluoride and sulfur dioxide on oxidative stress and antioxidant defenses in the testes, 96 sexually mature male Wistar rats were divided randomly into four groups of twenty-four rats each. One group of rats was left untreated as controls, and the other three groups were administered, respectively, for eight consecutive weeks, 100 mg NaF/L (45 mg F–/L) in their drinki...

The prediction of regional sulfur dioxide (SO2) emission of thermal power belongs to gray system which has small amounts of samples and little information, so a appropriate forecasting method is essential. Based on thermal power industry SO2 emission data from state department authorities, considering the main factors of China's thermal power industry SO2 predicted emission, we established a co...

There is controversy as to whether low levels of air pollution affect the symptoms and lung function in asthma. We addressed this by examining the short-term effects of winter air pollution on childhood asthma in Paris. We performed a 6 month follow-up of 84 medically diagnosed asthmatic children classified into two groups of severity. The outcomes included incidence and prevalence of asthma at...

Antitussive effects of ethyl acetate fraction of Terminalia chebula on sulphur dioxide (SO2) gas induced cough have been examined in mice. Safety profile of Terminalia chebula was established by determining LD50 and acute neurotoxicity. The result showed that extract of Terminalia chebula dose dependently suppressed SO2 gas induced cough in mice. Terminalia chebula, after i.p. administration at...

The assessment of atmospheric corrosion is currently based on studies basins (AB). models applied to the estimation imply measurements several meteorological and pollution parameters, which make complex. main parameters be considered in tropical are associated with temperature (T) relative humidity (RH). These also included calculation time humidification (TDH). In addition, pollutants chloride...
